https://devzone.nordicsemi.com/f/nordic-q-a/32615/getting-started-with-nrf51422-keil-v5-18a-w-s310Hi, I am having some issues. Just getting started with the nRF51422, so forgive my being a bit &quot;green.&quot; Background: Testing with nRF5_SDK_12.3.0_d7731ad, Keil V5.18A on the demo board PCA10028. I thought this would be plug and play?

I am still having some issues - sorry for the delayed response. I was pulled onto another task for a bit. Looking at your table, how do I know what revision of the IC I am using?&nbsp; I do not see an indication on the IC.</p> <p>The part number I see on the IC is &quot;N51422 QFAAF0&quot;</p> <p>I found this doc though -&nbsp;<a href="http://infocenter.nordicsemi.com/pdf/pcn_093_v1.1.pdf">http://infocenter.nordicsemi.com/pdf/pcn_093_v1.1.pdf</a>&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125455?ContentTypeID=1Thu, 22 Mar 2018 08:08:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:960a1bc3-59ef-454e-b4d1-ef0fca5b64d4Martin Lesund<p>Including the tips Jeff said, I would recommend you to take a look at <a href="https://devzone.nordicsemi.com/f/nordic-q-a/30338/getting-started-for-beginners" target="_blank" rel="noopener noreferrer">this post</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125426?ContentTypeID=1Wed, 21 Mar 2018 21:31:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b39dcb9-e791-4e53-a58d-c93c4b8579ddJeff4BLE<p>Please refer to &quot;<a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf51%2Fdita%2Fnrf51%2Fcompatibility_matrix%2FnRF51422_nRF51822_ic_rev_sdk_sd_comp_matrix.html">nRF51 Series IC revisions compatibility with SDK and SoftDevices</a>&quot; The S310 is not compatible with SDK 12.3.
